I spent so much time choosing my race, my clan, AND my guardian. They are barely noticeable, if at all. I would like if they had a little bit more sway, especially considering how high your base stats are at 50 (prior to point allotment) compared to, say, XI. Having a few points extra is negligible when you already have over 100 in each stat.

Today, an LS-mate asked me why my tail had a red tip, and I had to explain the difference between the two mi'qote races, and how I chose the keepers of the moon because I plan to be a mage. As of right now, clans don't matter at all. It would be nice if they were in the future.
